Spring Boot学习_springboot里面的item-优快云博客

本文详细介绍了如何在SpringBoot项目中编写单元测试类，通过使用@RunWith和@SpringBootTest注解，或继承测试主类并添加@Component注解来实现。以OrderDetailRepositoryTest为例，展示了如何保存OrderDetail对象，并使用JUnit的Assert断言验证结果。

1、如何写测试类？

添加如下两个注解

@RunWith(SpringRunner.class)
@SpringBootTest

或者继承测试主类，如：OrderApplicationTests，然后再加上@Component注解即可

案例

package com.imooc.order.repository;

import com.imooc.order.OrderApplicationTests;
import com.imooc.order.dataobject.OrderDetail;
import org.junit.Assert;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.math.BigDecimal;

@Component
public class OrderDetailRepositoryTest extends OrderApplicationTests {

    @Autowired
    private OrderDetailRepository orderDetailRepository;

    @Test
    public void testSave() {
        OrderDetail orderDetail = new OrderDetail();
        orderDetail.setDetailId("12367");
        orderDetail.setOrderId("123456");
        orderDetail.setProductIcon("http://xxx.com");
        orderDetail.setProductId("157875196366160022");
        orderDetail.setProductName("皮蛋粥");
        orderDetail.setProductPrice(new BigDecimal(0.01));
        orderDetail.setProductQuantity(2);

        OrderDetail result = orderDetailRepository.save(orderDetail);
        Assert.assertTrue(result != null);
    }

}
